Professional signaling tool for estimating Diameter Transactions Per Second (TPS) and peak bandwidth requirements for the S6a interface connecting LTE MMEs and HSS nodes.
S6a traffic modelers estimate Diameter TPS and bandwidth between MME and HSS from LTE/NSA mobility events—inputs you need before DRA and firewall sizing.

Feed into Diameter bandwidth and DRA dimensioning.
Run your own parametersThe model applies per-subscriber activity rates (Attaches/TAUs/Purges) to the total user base to derive the aggregate TPS. It then factors in average Diameter message sizes to estimate the required IP link capacity.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Compliant with 3GPP TS 29.272. Essential for avoiding signaling congestion during massive registration events or MME pool rebalancing.

1M subs × 0.25 attaches/sub/busy-hour ≈ 69 attaches/s. At ~6 Diameter messages/attach, base load ≈ 414 msg/s before TAUs and retries.
Feature-specific AVPs change sizes. Calibrate with HSS KPI exports.
Attach, detach, TAU, and authentication-related Diameter exchanges dominate. Roaming and flood events multiply baseline rates.
Use a procedure message count (often several request/answer pairs per attach including AIR/AIA, ULR/ULA, etc., depending on features) then multiply by busy-hour attach rate.
Yes for EPS-anchored NSA. Pure SA shifts analogous load toward AUSF/UDM HTTP APIs—model the architecture you run.
Convert between ITU, ANSI, and other SS7 point code formats.
